Contrary to the narrative the home Dorner was in was incidentally set ablaze by a flashbang or a "smoke device," interceptions from police scanners in the area indicate police executed an explicit "plan" to burn the house down.

First video:

"We're going to go forward with the plan, with the burner."

"...like we talked about."

"Burner deployed, we have a fire."

Second video:

"Burn it down."

"Go get the gas."

"Yea, burn it down."

Third video:

"Burn it!"

"Burn it!"

"Burn that motherf**ker down!"

Hopefully there was no innocent hostages in this house who were burned alive by the police, and hopefully this was actually Dorner and not another innocent bystander. The police have yet to enter the house to examine it's charred contents.
